CHANNEL-CUTTER.

SPECIFICATION forming part of Letters Patent No. 425,003, dated April 8, 1890.

Application filed October 25, 1889. Serial No. 328,191. (No model.)

To all whont it may concern:

Be it known that I, CHARLES FR. TH. SAL- GER, a citizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Shoe-Makers Tools, of which the following is a specification, reference being had therein to the action of. the channels and recesses to be cut,

but also for the depth of the same, and which will thus greatly facilitate and accelerate this part of the operation of shoe-makers; and with these objects in view my invention consists of the novel devices and combinations of devices hereinafter described, and specifically claimed.

In the accompanying drawings, Figures 1 and 2 represent side elevations, and Figs. 3 and 4: end elevations of the tool; Fig. 5, alongitudinal section through the center line of the tool; Fig.6, a detached view of one of the locking-latches; Fig. 7, a cross-section online or as in Fig. 1; Fig. 8, a bottom face View of the insole; Fig. 9, a similarview of the outsole; Fig. 10, a cross-section of the outsole on line y y in Fig. 9; and Fig. 11 a cross-section of the sole portion of a boot or shoe on line ,2 z of Fig. 8, showing the connection of the parts.

Corresponding referential characters in the several figures of the drawings designate like arts.

p The shank of this tool is composed of three members, 1, 2, and 3, all made of metal, and the middle member 2 being provided with flanges i to its edges for holding part 3 in line therewith, and these three members being connected in about their middle by a screw 5, passed through a slot 6 in member 3, through a hole in member 2, and tapped into member 1, whereby the member 3 can be longitudinally adj usted relative to the other members. The member 2 has a head 6 integral therewith, which head is transversely grooved in its middle, with a short squared projection 7 to one side and a longer tapering projection 8 to the opposite side of said groove, and with a slot 9 through head 6, extending angularly from the notch toward the shank through the base of projection 8, and through this slot 9 is placed a knife 10, being adj ustably secured therein by two setscrews 11, tapped through projection 8, and by a set-screw 12, tapped through the head 6 from the opposite side thereof to be central between the two set-screws 11. This knife 10 thus secured will occupy an angular position relative to the face of projection 7, with its cutting-edge projecting beyond such face'of projection 7 the desired distance the channel 13 in the bottom of the outsole 14 is to be cut, whereby the projection 8 will be guided against the edges of the sole 14 for gaging the distance the channel 13 is to be from such edges.

The end of member 2 opposite to its head 6 has in one face a recess for inserting therein one shank of an L or angularly shaped knife 15, while the end face opposite to such recess of member 2 is chainfered toward knife 15.

The part 16 of member 1, adjoining knife 15, is shaped rectangular with a blunt or stubbed end, and the knife 15 is clamped between the end faoes of members 1 and 2 by a screw 17, tapped into member 2 and passed through a hole in member 1 of the shank. This screw 17 being larger in diameter under its head, it provides a shoulder that bears upon member 1 for contracting the parts, while this larger diameter portion provides the pivot for a plate 18 to swing thereon, and to be either turned toward the shank of the tool, as in Fig. 1, or to be in line with part 16 of shank 1, as shown by Figs. 2, 3, and 5, with its exterior end extending beyond thi end of part 16, where it is securely held by having a projecting nose 19 entering a notch 20 of part 16 of such shank 1 and by a turnbuckle 21, pivotally secured against the edge of end 16 by a screw 22, tapped therein and turned to overlap the edge of plate 18.

The end of member 3 of the tool-shank butts against the inner face of the outer shank of knife 15, and is fitted to provide a true bearing for such knife end to rest against. This member 3, a short distance above its end, is provided with an eye-lug 23, against which eye-111g by a rivet is pivotally secured the eyed end of an L-lever 24 to swing thereon, the shorter angular shank of which L-lever 24: will turn over the end of the knife 15, and will be locked on this position by a turn buckle 25, pivotally secured against the end face of member 3 by a screw 26, tapped into member 3 so as to swing thereomwhich turnbuckle 25 has to its swinging end a rectangular flange 27, that with being turned outward will grasp the edge of lever 24, holding it from swinging and against lateral lost motion. For turning L-lever 24 to release and clear the knife 15, the turn-buckle 25 must be turned inward to be in line with the center line of the shank, and for enabling such movement a segmental groove 28 is formed in the edge of L-lever 24, and is continued in the end face of member 3 for clearing the flange 27 during the swinging movement of turn-buckle 25.

A set-screw 29, tapped through member 3, near the fulcrum of L-lever 24:, and butting with its point against member 2 of the shank, is for adjusting the width of knife 15 to be exposed by L-lever 24:, by spreading the members 2 and 3 more or less, for which purpose the screw 5 must first be loosened, and then after such adjustment must be drawn tight again, While, as already described, the slot 6 in member 3 will permit longitudinal adjustment of member 3 for varying the distance of the cutting-edge of the knife 15 beyond the stub end of part 16 of member 1.

The insole 30 for a boot or shoe is first to be formed in its lower face with a marginal recess 31, extending to the heel portion of such insole, which is accomplished with my tool by adjusting it, as shown by Fig. 1, with the plate 18 swung back, when that part of lever 2i projected over knife 15 will provide the guide-shoulder to follow the edge of the sole 30, and the stub end 16 of member 1 will form the gage for the depth the knife 15 is to reduce the sole 30. By this operation the corner of knife 15 will leave a shoulder 32, which for the next operation will be the guide for the tool for cutting a recess 33 in the inward face of sole 30. For this purpose the L-lever 24c is first released from turn-buckle 25, and is thenswung to clear knife 15, and then the plate 18 is turned outward and locked by turnbuckle 21, all as shown by Fig. 3, the projecting edge of which bar 18 will now be the guide to be moved along the shoulder 32, with the knife 15 reducing the insole to the depth the butt-end 16 will permit, thus leaving a ridge 35 on the sole of equal width and uniform distance from the outer edge of sole 30. U11- der the margin 31 of insole 30 is secured the edge of the upper 36 and of the welt 37 by transverse stitching through the ridge 35 from edge 34 to edge 32, and to the welt is then secured the outsole by stitching through the channel 13 of such outsole, which stitches afterward are covered and protected by closing the channel 13 in the usual manner. It will thus be readily seen that this tool is complete in itself for the several operations necessary for channeling and recessing the soles of boots or shoes, which work can thus be performed in the most accurate manner.

What I claim is- 1. In a tool for the purpose described, the combination of the members 1, 2, and 3 of the shank or handle adjustably connected by screw 5, of L-shaped knife 15., secured to member 2, and of .L-shaped lever 24:, secured to member 3 and overlapping knife 15 to provide a gage or guide shoulder, substantially as set forth.
